Title: Improvements in or relating to contact printing devices
IPC: G03B27/30
Filed: 1960-06-24
Abstract: 905,750. Contact printing apparatus. ZINDLER, W., [trading as LUMOPRINT ZINDLER KOMM.-GES.]. June 24, 1960 [July 6, 1959], No. 22173/60. Class 98 (2). A contact printing device has a cover which is located on the side of a transparent contact surface facing away from the light source, the said cover being tiltably and elevationally freely movable, and adapted to be yieldably pulled down on to the contact surface by a plurality of clamping devices, each incorporating a spring, so that the cover may adjust itself to the thickness of the copy; all the clamping devices are actuated by common means including a shaft passing from end-to-end through the compartment containing the light source. As shown, the apparatus comprises a lower chamber 2 containing the light sources 5, 6, and closed by a transparent cover 7 on which the original and copy sheets are placed. An upper chamber 3 contains a cover 12 which can be moved down to hold the sheets against the cover 7. The cover 12 is adjustable in a vertical direction, so as to accommodate any thickness of documents. As shown, the rear end 13 of the cover 12 has pivots 16 which move in guiding stirrups 15 secured to the wall 14 of the chamber. Thus the cover can move vertically while guided by the stirrups. Movement is imparted to the cover by a spring 20, attached to the cover by a pivot 21. The lower end of the spring is attached to an angled part 24 pivoted at 25 to an arm 26. The other end of arm 26 is fast with a shaft 34. Thus as shaft 34 turns, movement is transmitted by the linkage 26, 24, 20 to the cover 12. Also operated by shaft 34 is a further linkage system comprising arm 29, angled part 27 and a belt 18, 22. The belt 22 is also attached to the pivot 21, and runs over a roller 30. The shaft 34 extends through the whole width of the apparatus and through one of the side walls, so that it can be operated by an external crankhandle. Two such complete linkage systems are actuated by the shaft 34, one at each side of cover 12. As the shaft is rotated to one or other extreme position through 180 degrees, the cover is either raised to the position shown in the Figure, or drawn down into contact with the documents on surface 7. Since the rear end 13 is free to move vertically, the cover can adapt itself to the particular thickness of these documents, varying from single sheets to a thick book. Figs. 4 and 6 (not shown) illustrate some different methods of mounting the rear end 13 for vertical movement. A further chamber 4 may be provided above chambers 2 and 3, to house a developing apparatus 9. A timer for controlling the duration of exposure may be incorporated, and may be triggered off as the crank-shaft 34 is actuated.

Abstract: 625,636. Controlling aircraft. WILLIAMS, D. Aug. 13, 1947, No. 22511. [Class 4] An aircraft is provided with means for detecting relative twisting of parts of an aerofoil and for initiating in accordance with such twisting an operation for varying the lift or lift moment on the aerofoil to reduce the resultant air-loads thereon. In the arrangement shown, an open-sided torsion cell is provided near a wing tip, the relative movement of the opposite sides, due to twisting of the cell as the result of gusts, being utilized to move a load-relieving flap 8.- The cell is formed between spanwise and chordwise extending spars 2 and 5, 6 respectively by slitting the aerofoil skin at 3, 4 in a chordwise direction between the spar 2 and the trailing edge, and by slitting the latter between the slits 3, 4. A pseudo web 7, also slit in the spanwise direction, is provided near the trailing edge of the torsion cell, the relative movement of the two portions of the web being utilized to operate the flap 8, either directly or through a servomotor 9. A unit 10 is provided between the web 7 and servomotor 9 for differentiating between gradual changes of air load due to normal movements of the pilot's controls and sudden changes due to gusts, the latter only causing operation of the servomotor. As shown in Fig. 3, the unit 10 comprises a movable self-centring cylinder 11 containing a dashpot piston 12 and piston-rod 13. The latter is connected to the air load or gust responsive device and the cylinder is connected to the servo unit by a rod 14. The piston 12 moves freely in the cylinder 11 with slow changes of air load, but a sudden change results in movement of both the piston and cylinder to cause operation of the servomotor.

Title: Method of separating mixtures of particles into fractions according to specific gravity, and means therefor
IPC: B03B5/62
Filed: 1951-09-28
Abstract: 698,379. Washing granular materials. MAATSCHAPPIJ VOOR KOLENBEWERKING STAMICARBON N.V. Sept. 28, 1951 [Sept. 30, 1950], No. 22688/51. Class 82(ii) A method of separating a mixture of particles into three fractions of different specific gravities comprises feeding the mixture into a sink-and-float bath, passing the sink fraction into an upward current separator for separation into heavy and middle fractions, passing liquid separating medium continuously from the upward current separator into the sink-and-noat bath and continuously recirculating medium from the bath together with medium overflowing with the middle fraction to the separator, the medium in the sink-and-float bath and the upward current separator being held at different specific gravities by feeding correcting medium to the bath at a rate depending on the variation. of the specific gravity of the medium in the bath, and the medium recirculated to the upward current separator being thickened. In an apparatus shown for carrying out this method, raw coal is supplied at 1 to the sink-and-float bath 3, the coal being removed over the screening plate 4 and the shale and middle fraction lifted by a scraper and passed, via a trough 6 to an upward current separator 8 which is preferably of the type described in Specification 699,132. The middle fraction overflows at 9 and the suspension draws off through a screen 10 to a pump 12, any further suspension being rinsed off on a screen 14 and the diluted suspension thickened in a cyclone 28, the output of which also passes to the pump 12. The suspension rinsed from the shale on screen 16 is thickened in a cyclone 29 and that rinsed from the coal on screen 5 thickened in a cyclone 27, both the thickened suspensions passing to the pump 12. From the pump 12 the suspension is returned to the separator via the pipe 13 and to an overflow chamber 17 on the separator, via a pipe 18, from which chamber some passes into the separator and some passes through an overflow pipe 20 to the bath. The specific gravity of the suspension in the sink-and-float bath may be reduced by the addition of water or dilute suspension at 22, which additions may be automatically controlled by a device described in Specification 608,876, [Group XXIX]. Fine coal contained in the suspension rinsed from the coal is removed by a froth flotation machine 33 and suspension losses are compensated at 37 and any surplus liquid drained off at 38. The cyclones 27, 28, 29 may be replaced by a single cyclone. Specification 465,126 also is referred to.

Abstract: 598,626. Internal shoe brakes. TIMKENDETROIT AXLE CO. Sept. 6, 1945, No. 22949. Convention date, Dec. 22, 1944. [Class 103 (i)] In brakes of the character disclosed in Specification 576,503 the brake spider or foundation member 10, Fig. 1, is rigidly secured to the axle housing 15, Fig. 6, by being bolted to an adaptor flange 14 welded at 16 to the housing. Four anchor pins such as 26 are received in apertured bosses 18 of spider 10, and two shoeoperating levers 34, 35 are pivoted at their lower ends on neighbouring anchor-pins. The upper ends of levers 34, 35 are swung outwardly to operate the shoes by spreading means comprising a hydraulic cylinder 94 mounted on a bracket 89 secured by apertures fitting over the upper pair of anchor-pins. The saddle bar 48 of each of the levers 34, acting upon pressure block 56, is slightly inclined to the normal so that during lever movement in operating the shoes the bar passes intermediately through the normal position thus avoiding undue inclination at any time and the consequent loss of braking force. Adjustment of shoe and lever components for shoe lining wear is produced by rotating the lower anchor pins 26, shown in section Fig. 2 as having a circular eccentric part 74 fitting an aperture in shoe abutment 40 and moving it together with an abutment at the upper end of the shoe to force the shoe radially outward; the shoe-operating lever 35 is simultaneously adjusted by the eccentric. Pneumatic means for actuating the shoe-operating levers is shown in Fig. 6; a pneumatic actuator causes rotation of a shaft 142 having an end enlargement 154 slidably engaging, as shown in Fig. 11, with a resiliently-mounted head 158 carrying pivoted levers 172 connected to levers 35, the force on the levers 35 being automatically adjusted to equality. A modification is described where the adjustment is produced solely by sliding engagement of parts. Bracing levers 77 connect the upper and lower pairs of anchor-pins. The inner wheel rim 116 of a dual wheel arrangement is shown in Fig. 6 with its drum 134 secured by bolt 136 (which also secures the drum of the outer wheel not shown) to wheel hub 118, which is rotatably mounted on a sleeve 120, borne by housing 15, and is connected to an axle shaft 128. A dust shield may be secured to housing 15 at the open end of drum 134; if this is omitted drum apertures 140 serve to admit cooling air, the edge of spider 10 being spaced from the drum to allow axial flow.
